Machine learning apparatus, controller, generation method, and control method

A machine learning apparatus that generates a learning model configured to estimate a cutting condition when performing a cutting process on a workpiece using a tool, the machine learning apparatus comprising:

• a first information acquiring unit configured to acquire first information including at least one of a shape of the workpiece, a material of the workpiece, a cutting path of the cutting process, a type of the tool, and an amount of wear of the tool;
• a second information acquiring unit configured to acquire second information correlated with an evaluation of a burr occurring on the workpiece due to the cutting process;
• and
• a learning unit configured to execute learning processing using a plurality of pieces of the first information and a plurality of pieces of the second information, and generate a learning model configured to output the cutting condition, according to another piece of first information that is different from the plurality of pieces of first information.
